Altered connectivity was also found in the ADHD group between NAcc and posterior insula, a region implicated in various functions, including emotional processing and sensory-motor processing (Chang et al., 2012), and previously shown to present atypical functioning in ADHD (Valera et al., 2010). Interestingly, an increased connectivity between NAcc and insula was found by Di Martino et al. (2011) in children with autism, a disorder that shares several behavioral characteristics with ADHD.
